The UK is among 11 countries where users of Opera's mobile browser, Opera Mini, surpassed one million this year.

According to the browser developer's State of the Mobile Web report for October, the UK hit one million users in January 2011. Meanwhile, Turkey, Egypt and Mexico were among the countries that hit the one million user mark later in the year.

Opera said more than 140 million people used Opera Mini in October this year, which is 83 percent up on usage figures from the same time last year. Furthermore, usage of the mobile browser has doubled eight times since its introduction in January 2006.

Opera said the mobile browser, which features Opera Turbo to compress the bandwidth of text and data files on websites by up to 80 percent, was used to view 86 billion pages throughout the month, 107 percent up on last year. Those page views accounted for almost 13 petabytes of data, which was subsequently reduced to just 1,335 terabytes thanks to Opera Turbo. Over the past 12 months, data usage has surged by 121 percent.

"Opera Mini has gained users in every country, across 2G, 3G and 4G networks, across feature phone and smartphones," said Lars Boilesen, CEO, Opera Software.

"What these numbers won't tell you is that many people use Opera Mini as their only means to get online. We're seeing a whole new generation of people connect to the web for the first time using a mobile device and we are only starting to see the changes -- societal, technological, and cultural -- that will happen as a result."
